Description

Technical Field

[0001] The invention belongs to the technical field of security cameras and relates to a security camera that is easy to maintain. Background Art

[0002] Security cameras are cameras used for security purposes. Their key features include high sensitivity, strong light resistance, minimal distortion, compact size, long lifespan, and vibration resistance, leading to their widespread use. Surveillance cameras are semiconductor imaging devices. In security systems, images are primarily generated by CCD cameras. They can also extract stored charge to generate voltage fluctuations, making them widely used due to their vibration and impact resistance. Color cameras are suitable for identifying detailed details, such as the color of clothing or scenery.

[0003] Existing security cameras need to be maintained regularly when used for a long time. A common maintenance item is to remove dust from the camera equipment. At the same time, existing security cameras use passive heat dissipation, and it is necessary to regularly check whether the temperature of the security cameras is too high. When existing security cameras are used outdoors, water droplets are easily left on the front end of the camera on windy and rainy days, thereby affecting the operation of the camera. Therefore, we propose a security camera that is easy to maintain. Summary of the Invention

[0004] The purpose of the present invention is to address the above-mentioned problems in the existing technology and to propose a security camera that is easy to maintain. The technical problem to be solved by the device is: how to make the security camera easy to maintain.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] A security camera that is easy to maintain includes a camera assembly, which includes a lens and two mounting plates. Several heat sinks are fixed between the two mounting plates, and the heat sinks are U-shaped. An image processing box and two PCB boards are fixed inside the several heat sinks. The two PCB boards are respectively fixed at the upper and lower ends of the image processing box. The two PCB boards are in contact with the heat sinks through thermal conductive silicone pads. The lens is fixed at the end of one of the mounting plates, and the lens, image processing box and two PCB boards are electrically connected. Snap-on plates are clamped on the sides of the two mounting plates, and a guide assembly is provided above the two snap-on plates. A dustproof assembly is provided inside the guide assembly, and the dustproof assembly is located at the end of the lens. A protective baffle is provided above the guide assembly, and a wiping assembly is provided below the two snap-on plates.

[0007] The working principle of the present invention is as follows: the heat generated by the image processing box and the two PCB boards is transferred to the heat sink through the thermally conductive silicone pad, and then dissipated to the air through the heat sink. The wiping component transports filtered air to the plurality of heat sinks, and the filtered air transports the high-temperature air to the guide component. The guide component transports the high-temperature air to the dust-proof component, thereby preventing the dust-proof component from being easily contaminated with dust and extending the maintenance cycle. The high-temperature gas can blow off raindrops on the dust-proof component on windy and rainy days. At the same time, the high-temperature gas can quickly dry the water stains left by raindrops without affecting the use of the security camera. When the dust-proof component is contaminated with a lot of dust, the wiping component wipes the dust-proof component, thereby extending the maintenance cycle.

[0008] The guide assembly includes a guide box, which is fixed above two buckle plates, and an air outlet and a heat dissipation outlet are provided below the guide box. A first filter is provided inside the air outlet, and the heat dissipation outlet is located above a number of heat sinks. Two guide plates are fixed below the guide box, and two second rotating rods are rotatably provided inside the guide box. A clamping rod is provided inside the guide box.

[0009] With the above structure, high-temperature gas enters the interior of the guide box from the heat dissipation port, and is then transported to the air outlet through the guide box. The high-temperature gas is finally blown toward the dust-proof component through the air outlet, thereby preventing the dust-proof component from being easily contaminated with dust and extending the maintenance cycle. The high-temperature gas can blow off raindrops on the dust-proof component on windy and rainy days. At the same time, the high-temperature gas can quickly dry the water stains left by raindrops without affecting the use of security cameras.

[0010] The wiping assembly includes an installation box, which is fixed under the two buckle plates. A collection box and a feed box are clamped under the installation box. A spring is fixed inside the feed box, and an extrusion plate is fixed at the end of the spring. The extrusion plate is slidably arranged inside the feed box. Two sliding grooves are provided inside the installation box, and a partition and a second motor are fixed inside the installation box. The second motor is fixed on the inner wall of the installation box. The output shaft of the second motor is connected to a threaded rod, and a push plate is screwed on the threaded rod. The cross-section of the push plate is U-shaped, and the push plate is slidably arranged on the two sliding grooves. Two first rotating rods are rotatably arranged inside the installation box.

[0011] With the above structure, when maintenance is required, the collection box and the feed box are removed, the wiping sponge inside the collection box is taken out for cleaning, and then the clean sponge is placed inside the feed box. Finally, the collection box and the feed box are clamped under the installation box to complete the maintenance.

[0012] An air inlet is provided below the installation box, a second filter is fixed inside the air inlet, a fan is fixed inside the installation box, the fan is located directly above the second filter, a connecting port is provided above the installation box, and the connecting port is located below the plurality of heat sinks.

[0013] With the above structure, the fan draws air from the air inlet to the connecting port, the second filter filters the dust and moisture in the air, and the air is transported to the plurality of heat sinks through the connecting port, and the plurality of heat sinks dissipate heat into the air.

[0014] The dustproof assembly includes a dustproof sheet, a first motor and two rotating shafts, which are rotatably arranged on the guide box and the guide plate respectively. Two gears are fixed on the two rotating shafts. The first motor is fixed on the outside of the guide box, and the output shaft of the first motor is connected to the rotating shaft on the upper side through a coupling. A limiting groove is provided under the dustproof sheet, and the clamping rod is slidably arranged inside the limiting groove. The dustproof sheet is made of elastic transparent material. Two elastic racks are fixed under the dustproof sheet, and the two elastic racks are engaged with the gears at corresponding positions. The lower end of the dustproof sheet is placed on the two first rotating rods.

[0015] With the above structure, the first motor drives the rotating shaft to rotate, the rotating shaft drives the gear to rotate, the gear drives the elastic rack to move, and the elastic rack drives the dustproof sheet to move, thereby moving the dustproof sheet with dust to the inside of the installation box. The clamping rod and the limit slot cooperate to limit the dustproof sheet to prevent the dustproof sheet from tilting.

[0016] Compared with the existing technology, this easy-to-maintain security camera has the following advantages:

[0017] 1. The dustproof component, guide component and wiping component work together to automatically clean the dust on the dustproof sheet, thereby extending the maintenance cycle of the security camera. At the same time, the collection box, feed box and installation box work together to quickly replace and clean the collection box and feed box, making it convenient for maintenance personnel to maintain the security camera;

[0018] 2. The camera component, guide component and wiping component work together to continuously dissipate heat from the image processing box and PCB board to prevent the internal temperature of the security camera from being too high. BRIEF DESCRIPTION OF THE DRAWINGS
